She may regret letting Frea be in charge of keeping track of things. Organization isn't one of her greatest skills. That said, she'll be keeping track of Brienne as best she can. Brienne's wellbeing is important.

They might need to find Brienne some other clothes. There's less need for leather and steel around the Nexus, and it's going to get so hot over the summer. Nobody wants a Broiled Brienne.

Brienne might be used to ordering servants around, but Frea asks for things politely, with a smile, and with thanks and compliments when they're delivered. And, of course, prompt payment.
